Error messages In addition to the displayed error messages, the red LED “Alarm” lights up or flashes. Alternate display of all error messages and operating displays. Each occurred error is stored in the error history. Error message “Power failure” Power failure Power failure set clock ! Message after each switching on, unit was without voltage. - Page 9 Error Message “CD2 Max” CD2 Max Conductivity CD2 is greater than the set limit value “CD2 Max” CD2: 32.1 : S/cm The maximum conductivity at sensor CD2 has been exceeded for a longer period than the programmed test time (Delay Max) during production.
- Page 10 Error message “Excess pressure” Excess pressure The pressure switch behind the pressure pump for the protection of the units CD1: 16.8 : S/cm against excess pressure has triggered. The plant has been switched off after the programmed delay time (Delay HP). Restart the plant via the "RUN/STOP" key. If renewed excess pressure occurs, the plant is switched off again after the delay time.
